Veo 3.1 was more reliable here. Grok Imagine Video 1.5 caught the crate vault in the chase and gave the glass strawberry a lovely pink glow, but its zombie already had cracks in the first frame and barely changed, and its ASMR sound was the quietest of the group. Grok runs longer, up to 15 seconds.

Night, a narrow Hong Kong-style alley in heavy rain, red and teal neon reflecting in deep puddles. A young woman in a yellow raincoat sprints toward the camera, glancing back and shouting "They're right behind me!"; two figures in black coats chase her, splashing through the puddles. Handheld tracking shot moving backward at running speed, then a whip pan as she vaults a stack of wooden crates. Steam rises from a street-food stall; a hanging lantern swings as she brushes past. Sound: pounding rain, splashing footsteps, ragged breathing, distant sirens.
Close-up of a smiling man in his late twenties in a knit sweater by a window at dusk, jack-o'-lanterns glowing on the sill. He says quietly, "Something's wrong... I can't feel my hands." Green fog drifts in and the lights flicker. In one continuous shot his skin turns ashen grey, dark veins spread from his neck to his cheeks, his eyes cloud to milky white and his smile stiffens into a snarl, while the camera pushes in slowly. Sound: low wind, a buzzing bulb, a final guttural growl.
Extreme macro on a wooden cutting board: a knife slowly slices a strawberry made of clear glass, then a kiwi made of translucent amber glass. Each cut reveals glittering inner facets and tiny trapped bubbles; thin glass slices tip over and clink together. Soft studio light, shallow depth of field, slow dolly to the right. Sound: crisp glass crunching, delicate clinks, quiet room tone.
A skydiver in a red jumpsuit falls through towering sunset clouds, arms spread. The camera orbits half a circle around her, then dives with her through a cloud layer into golden light, revealing sea cliffs and a turquoise ocean below. Her jumpsuit ripples violently, hair whips across her goggles, god rays cut through the vapor. Sound: roaring wind, flapping fabric, a rising orchestral swell.

Yes. Both spoke the scripted lines in the chase and zombie prompts; Grok's mix was quieter overall.
